Introduction
The Lindeniidae was formerly regarded as a subfamily of Gomphidae under its junior synonym of Ictinogomphinae. Bechly (1996) accorded it family status and included the nine genera listed under Lindeniini by Bridges (1994). The only included Australian genus is Ictinogomphus Cowley with three species distributed mostly across the north of the continent.
Watson (1991) revised and provided a key to the Australian species under the gomphid subfamily Ictinogomphinae. Hawking & Theischinger (1999) give an illustration and description of the larva of Ictinogomphus australis (Selys).
Diagnosis
Adult: eyes widely separated; occiput ridged, not tumid posterior to eyes; basal subcostal crossveins absent; hind wing with distal costal brace nearer proximal costal brace than to nodus; costa curved and widened along pterostigmata; pterostigmal brace present; subtriangle with crossveins; CuP and A slightly divergent to hind wing margin; anal brace present; fore wing without trigonal plate, base of distal pleat asymmetrical and closer to posterior end of subnodus than to distal angle of triangle; 3-9 postmedian crossveins; basoventral suface of hind femora without overlapping flat-appressed spines; auricle strongly dorsoventrally compressed and produced posteriorly in male, absent in female; anterior lamina not raised with medial seam, bilobate (Carle 1986).
Larva: prementum flat; ligula without median cleft and lacking prominent denticles; labial palps without palpal setae and end hook; antennae 4-segmented; all tarsi with 2 segments only; tibiae without distal spur or digging hook; wing-pads parallel; abdomen almost as wide as long; with lateral and mid-dorsal spines (Hawking & Theischinger 1999).
